Trump 'welcome' in Australia: politicians

US President Donald Trump would be welcomed by both Liberal and Labor if he decides to visit Australia during a tour around the APEC meeting in Papua New Guinea in November.

Mr Trump, along with other world leaders, is expected to make stops in Australia as part of a tour that will take him to the Asia-Pacific Economic Co-operation leaders' summit in Papua New Guinea on November 17 and 18.

One option being considered is Mr Trump visiting Sydney, Canberra and Cairns, but nothing had been "locked in" yet, a US government source told The Australian newspaper.

Federal cabinet minister Christopher Pyne said any president of the United States is welcome in Australia, despite a high chance of protests.

"We have 100 years of mateship with the United States this year, of course we would welcome him here," Mr Pyne told reporters in Adelaide today.

Labor Deputy leader Tanya Plibersek also welcomed the visit, but said Australia shouldn't be "unquestioning allies" of the United States. Picture: AAP (AAP)

"There's almost always protests when an American president visits Australia."
